City of Idaho Falls’ Updated Impact Fees Go into Effect June 1

The City of Idaho Falls is notifying developers, builders, and the public of upcoming changes to the City’s residential impact fee assessment structure that will take effect June 1, 2026.

Impact fees help fund the infrastructure and public facilities needed to support new development, including parks, transportation systems, and public safety facilities. They help ensure growth pays for growth, rather than shifting the cost of new infrastructure and public facilities onto existing taxpayers.
